>I think I'll get one of those OM13058s,Yes, thats a really nice board.

For many cost sensitive applications it would be usedful to have just the chip like the LPC810. It costs only around 80 EuroCent.Here I made an instruction guide on how make an LPC810 programmer with an Arduino Due:http://www.hobby-roboter.de/forum/viewtopic.php?f=4&t=152&p=602#p602

>I've been looking at the SAM D21 of late as well, great features but the registers are a real cluster f*ck. Isn't it comming with the Arduino Zero?

would it be possible to use the Arduino IDE ( for Arduino DUE ) to compile the code for the LPC810 ?

Not as it is, I think you would have to add your own variant file and core libraries but that's not an area I'm very familiar with.

@Bob/Chris, is it worth trying to develop an LPC Arduino port that will support several versions of LPC? It's certainly been an interest of mine but TBH I'm probably more HW than SW. I can certainly write code (was employed to do so for many years) but it's the toolchain stuff and organisation of files to allow all different CPUs that I struggle with.

Yes and yes! Struggling with toolchains is right up my creek. I have been wanting to get more into extending Arduino IDE so I decided to bite the bullet and have a go. Arduino 1.5.x makes it quite easy, it already has GCC-ARM compiler.

So what I did is take Chris's code and with a few minor changes put it into an Arduino structure. Seems to build OK with the Arduino 1.5.7 IDE but I don't have an 810 to test with. (I've got nearly a dozen LPC dev boards, but nothing with 8xx series, so I have ordered one from ebay.) I haven't looked at uploading, this was more of a test of the concept.

It actually went better than I expected, the Arduino team have made it really easy! Most of the code went into LPC8/cores/lpc810 and the Arduino framework builds it automatically. It should be easy to create new core types and board variants.

I'm not sure where example sketches should go, I compiled the blink sketch for 810 with a small change (include of sketch_ino.h not required), I haven't tried the others.

Thanks, I really just rearranged it

I think it is fairly essential that the git folder structure reflects the target structure, i.e. a user can do a git pull and then copy the tree to Arduino folder. Otherwise it is a nightmare to manage. git doesn't provide an easy way to link files that have the same content, so it's best to copy the ones that are needed to the new place.

Collaboration can be done in github with pull requests which is good for large projects with lots of contributors, but does have more overhead. A lighter method is to specify named collaborators who have full access equivalent to the repo owner., or most often a combination of both.

We could also set up an "Organization" which would perhaps be a cleaner way to do it, I haven't tried that before. Looks pretty easy though. We need to think of a good name for it...

I just ordered two 11U68 Xpresso boards (OM13058), they have Arduino headers so would be suitable for a port. But while there I noticed that the "LPC800 / LPC812 MAX Board" has Arduino headers as well.

And there's the Arch board as well, that's 3 CPUs at least, plus I already have code for the 1227, and it looks like there are other Xpresso boards with Arduino headers, the LPC1549 for example

So far we're talking about maybe 3-5 CPUs, does anybody know if the peripherals are the same? Or does that mean 3-5 separate cores?

As for the Git stuff the "Organisation" sounds ok but as mentioned I have no idea about this stuff.

IF anything is going to happen though some organisation is required and also some deep thought to try and make a platform that can be used with all LPCs, or at least a good cross section of the models.

I know almost nothing about Git except that it's totally unintelligible, it's a miracle I got those files up at all

My code has a LOT of stuff for error handling etc. For example every "thing" is an object (well it's C so a structure) with guard bytes at each end and a type byte, all functions that use that object test those bytes.

This is way over the top for the average Arduino project and too heavy for the 800 (about 26k last I looked I think, but that includes a LOT of code for strings etc that is non core). But my goal at the time was to make a framework that was more industrial strength.

Note that there are a lot of debugging calls to toggle pins (pin14high(); for example), ignore them.

So far we're talking about maybe 3-5 CPUs, does anybody know if the peripherals are the same? Or does that mean 3-5 separate cores?

IME peripherals are only identical within CPU families, e.g. LPC13xx, and may be similar or just quite different between families, so LPC11xx has some completely different peripherals to LPC13xx. e.g. the gpio block is a lot simpler. I haven't looked in detail across the range.

So it might be difficult to create a common library. I still think it is useful to have a single "LPC support package" though. Perhaps the point of commonality is the Arduino API, so at least users can move from one LPC to another with relative ease.

I'd be happy to set up and coordinate github activity. I think I will set up my own repo anyway and anyone can fork it as they wish, and I'd be quite happy to give people access.

Git has a lot of "advanced" features, more than I can fully understand, so I tend to use 2 or 3 basic operations and keep it simple. Github also has some great features which are quite easy to use, like the issue tracker.

I would like to set up a framework for other LPCs, and write some Arduino libs for the ones I have. Microbuilder have some good code, I think that could be a good starting point.

But when I press "compile", I get the following error:/home/.../arduino-1.5.7/hardware/OpenNxp/LPC8/cores/lpc810/arduino.c:12:21: fatal error: arduino.h: No such file or directory #include "arduino.h"

Where do I have to place the missing header files?

Sorry, that's a problem with case-sensitive file names, in Windows I get lazy. In file "OpenNxp\LPC8\cores\lpc810\arduino.c", it should include "Arduino.h" not "arduino.h". I think that is the only place.

> should include "Arduino.h" not "arduino.h". IOK, now it's compiling.If you want, you can setup the main repository in github. The question is, how can we get my existing library into it. The next two days I will probably be off, so I will answer later.

I have now set up a github repo https://github.com/bobc/OpenLasp.

I'm not sure what you mean about your existing library, I've already incorporated it! I had to make a few changes, e.g. because an Arduino sketch is a C++ program. So you will probably want to keep your standalone LPC810 repo separate.

I'll get the upload tool working next.

Hi Bob,wow ... in your GitHub repo I saw that you have been quite busy. You even have started the LPC11 part. I just forked the repo and I will play around a little bit.Do you have meanwhile some LPC810 hardware and could you test some code?

What IDE or editor are you using? I started with a simple editor and a make file. And I tried the GIT command line. This was very complicated.But later I began to use Eclipse. There is a plugin called EGit. With this it is really easy to use git. You just right click on the file
